Iraq deeply mistrusts private security companies and wants to limit their operations here, officials say, while the contractors themselves have faced bureaucratic delays and detentions. This mistrust stems from perceived arrogant behaviour by employees of these firms in the past and various incidents of violence involving them..."Iraq is not looking to expand the security companies' work here," government spokesman Ali al-Dabbagh said..."Iraq has got a not friendly history with the security companies...So, we would like to limit their work here in Iraq, but we don't want to stop them," Dabbagh said..."They are not exempted as before, and they are not getting any sort of immunity," he said.
